Photos: Tuesday’s Atlas 5 rollout

A United Launch Alliance Atlas 5 rocket blasted off at 6:18 a.m. EDT (1018 GMT).to deploy the Navy’s fourth MUOS satellite that will expand coverage to encompass the globe with mobile communications.

Streaking away from Cape Canaveral less than an hour before sunrise Wednesday, an Atlas 5 launcher painted a memorable spectacle in the skies over Florida, catching the first rays of the morning as it rocketed out of the stratosphere with a U.S. Navy communications satellite.

The launch of NASA’s Mars 2020 rover is less than a year away, and the steady pace of work inside the craft’s pristine assembly hall in California is keeping the mission on schedule for liftoff from Cape Canaveral next July, despite growing costs, according to mission managers.
